Palladium-catalyzed oxidative annulation via C-H/N-H functionalization: Access to substituted pyrroles
Pyrroles, ubiquitous bioactive heterocycles in nature, are readily prepared via a palladium-catalyzed oxidative annulation of cyclic trans-enamines to various internal alkynes in the absence of a directing group. Copyright
